DESCRIPTION OF EMBODIMENTS

FIG. 1 is perspective diagram illustrating an engaging structure according to an embodiment of the invention. FIG. 2 illustrates a scenario that an engaging component of FIG. 1 is separated from the second object. Referring to FIG. 1 and FIG. 2, an engaging module 100 of the present embodiment is suitable for a first object 50 and a second object 60. The engaging module 100 includes an engaging component 110, an elastic component 120 and at least one electromagnet 130 (illustrated as two in this case). The engaging component 110 is movably disposed on the first object 50, and a material of the engaging component 110 includes a magnetized material. The elastic component 120 is connected between the engaging component 110 and the first object 50, and the electromagnets 130 are disposed on the first object 50.
FIG. 3 is a cross-sectional diagram of the engaging structure illustrated in FIG. 1. FIG. 4 is a cross-sectional diagram of the engaging structure illustrated in FIG. 2. When the first object 50 and the second object 60 are combined, the engaging component 110 is adapted to move to a first position P1, as shown in FIG. 3 and to be positioned at the first position P1 through an elastic force of the elastic component 120. In this scenario, the engaging component 110 is engaged with the second object 60, such that the first object 50 and the second object 60 are fixed to each other. Additionally, when the first object 50 and the second object 60 are combined, the electromagnet 130 is energized, such that the electromagnet 130 generates a magnetic force, such that the engaging component 110 resists the elastic force of the elastic component 120 through the magnetic force generated by the electromagnet 130, as shown in FIG. 4, to move to and be positioned at the second position P2. In this scenario, the engaging component 110 is separated from the second object 60, such that the first object 50 and the second object 60 may be separated from each other.
Under the aforementioned disposition, the first object 50 and the second object 60 are assembled dissembled by the engaging module 100 through the movement of the engaging component 110, rather than through deformation of a hook in the way like the conventional hook does. Thus, the amount of interference between the engaging component 110 and the second object 60 interfered with each other is not limited to have larger amount of engagement and therefore, have better engaging capability. In addition, since the engaging module 100 is not operated through the elastic deformation of the engaging component 110 as described above, the minimum length of the engaging component 110 is not limited by the need of the elastic deformation, which contributes to thinning the appearance of an apparatus applying the engaging module 100. Moreover, in the engaging module 100, the engaging component 110 is driven to move by using the magnetic force generated by the electromagnet 130, instead of by using a force applied by a user, and thus, the engaging component 110 may be prevented from being fractured due to the force applied by the user. Meanwhile, the engaging component 110 does not have to be exposed for the user to apply the force, such that the apparatus applying the engaging module 100 may have better appearance.
To make the illustration more concise and clear, only partial structures of the first object 50 and the second object 60 are shown in the drawings. In the present embodiment, the first object 50 and the second object 60 may be, for example, two casings of an electronic apparatus. In other embodiments, the first object 50 and the second object 60 may be individually a display panel and its corresponding casing, a tablet computer and its corresponding docking station or any other objects that may be assembled to or disassembled from each other, which are not limited in the invention.
In the present embodiment, the first object 50 and the second object 60 are adapted to be combined or separated along a first axial direction D1. The engaging component 110 is adapted to move to the first position P1 and the second position P2 along a plane S, where the plane S is, for example, a structure surface of the first object 50 or any other adaptive reference plane. The first object 50 and the second object 60 are combined or separated along a direction (i.e., the first axial direction DO perpendicular to a moving plane (i.e., the plane S) of the engaging component 110, such that the engaging component 110 will not be driven by the relative movement of the first object 50 and the second object 60 along the first axial direction D1 to reduce the risk of the engaging component 110 being accidentally separated from the second object 60. In other embodiments, the first axial direction D1 is not necessarily perpendicular to the plane S and may be any other adaptive direction that is not parallel to the plane S.
The combination of the first object 50 and the second object 60 will be described with reference to the drawings. FIG. 5A and FIG. 5B are schematic diagrams illustrating a flow of combining the second object of FIG. 3 with the first object. In the present embodiment, the second object 60 has an engaging slot 62, and the engaging component 110 has a guide surface 110 a. The guide surface 110 a is inclined with respect to the first axial direction D1 and the plane S. When a user wants to assemble the second object 60 to the first object 50, the user may move the second object 60 along the first axial direction D1 toward the first object 50, as shown in FIG. 5A to FIG. 5B, such that the second object 60 pushes the guide surface 110 a of the engaging component 110 to drive the engaging component 110 to resist the elastic force of the elastic component 120 to move to the second position P2, as shown in FIG. 5B. Then, when the second object 60 continues to move along the first axial direction D1 to be combined with the first object 50, as shown in FIG. 3, the engaging component 110 is aligned to the engaging slot 62 of the second object 60 and moves to the first position P1 through the elastic force of the elastic component 120 to be engaged in the engaging slot 62. Thereby, the assembly of the first object 50 and the second object 60 is completed.
Furthermore, an engaging direction (i.e., a second axial direction D2) of the engaging slot 62 of the second object 60 is, for example, perpendicular to the direction (i.e., the first axial direction D1) for assembling/disassembling the first object 50 and the second object 60, such that the engagement of the engaging component 110 and the engaging slot 62 may securely stop the first object 50 and the second object 60 from being separated from each other. Accordingly, in the present embodiment, the direction (i.e., the first axial direction D1) for assembling/disassembling the first object 50 and the second object 60 is designed as being perpendicular to the moving plane S of the engaging component 110, such that the moving direction of the engaging component 110 is parallel to the engaging direction (i.e., the second axial direction D2) of the engaging slot 62 of the second object 60. Thus, the engaging component 110 may be smoothly engaged in the engaging slot 62 of the second object 60 along the second axial direction D2, without being designed in a form of a bending hook. Thereby, the issue of the hook fracture resulted from stress concentrated at the bending portion of the hook may be avoided.
Hereinafter, each component of the engaging module 100 of the present embodiment will be described with reference to the drawings. FIG. 6 is an exploded diagram illustrating the engaging module and the first object of FIG. 1. Referring to FIG. 1, FIG. 3 and FIG. 6, in the present embodiment, the engaging component 110 includes a main body 112 and a magnetized member 114. A material of the main body 112 is, for example, plastic or any other type of non-magnetized material. The main body 112 has a containing slot 112 a. The magnetized member 114 is made of, for example, iron or any other magnetized metal and disposed in the containing slot 112 a, such that the engaging component 110 may move to the second position P2 through the magnetic force of the electromagnet 130 attracting the magnetized member 114.
The first object 50 has two sliding slots 52 and a recess 54. The main body 112 of the engaging component 110 has two sliding blocks 112 b and a pillar 112 c. The two sliding blocks 112 b slide along the second axial direction D2 in the two sliding slots 52, and the pillar 112 c slides along the second axial direction D2 in the recess 54. In this case, the second axial direction D2 is parallel to the plane S. In other embodiments, the engaging component 110 may be slidably disposed on the first object 50, which is not limited in the invention. Additionally, the elastic component 120 is a compression spring fitted around the pillar 112 c, and the two electromagnets 130 are respectively located at two opposite sides of the pillar 112 c to generate an even magnetic force to attract the engaging component 110 and drive the engaging component 110 and the elastic component 120 to operate smoothly.
Each of the electromagnet 130 includes a magnetized member 132 and a coil 134. The coil 134 is wrapped around the magnetized member 132 and adapted to receive electricity to generate a magnetic field, such that the magnetized member 132 is magnetized to generate a magnetic attracting the engaging component 110. Additionally, the first object 50 has two fixing slots 56, each magnetized member 132 has a fixing portion 132 a, and each fixing portion 132 a is fixed to the corresponding fixing slot 56.
FIG. 7A is a partial schematic diagram illustrating the first object and the second object of FIG. 3. FIG. 7B is a partial schematic diagram illustrating the first object and the second object of FIG. 5A. Referring to FIG. 7A and FIG. 7B, in the present embodiment, the engaging module 100 (illustrated in FIG. 1 to FIG. 6) further includes a first electrical connection portion 140 a and a second electrical connection portion 140 b. The first electrical connection portion 140 a is disposed on the first object 50 and electrically connected with the electromagnets 130 (illustrated in FIG. 1 to FIG. 6). The second electrical connection portion 140 b is disposed on the second object 60 and electrically connected with a power supply. When the first object 50 and the second object 60 are combined, as shown in FIG. 3 and FIG. 7A, the first electrical connection portion 140 a contacts the second electrical connection portion 140 b. In this scenario, the electromagnets 130 are adapted to receive electricity from the power supply through the first electrical connection portion 140 a and the second electrical connection portion 140 b to generate the magnetic force to drive the engaging component 110 to separate from the second object 60. When the first object 50 and the second object 60 are separated, as shown in FIG. 5A and FIG. 7B, the first electrical connection portion 50 does not contact the second electrical connection portion 60 to prevent the electromagnets 130 from being overheated due to continuously receiving the electricity from the power supply through the first electrical connection portion 140 a and the second electrical connection portion 140 b. In other embodiments, whether the electromagnets 130 are energized may be controlled by other adaptive switches or sensing elements, which are not limited in the invention.
FIG. 8 is a perspective diagram illustrating an engaging structure according to another embodiment of the invention. FIG. 9 illustrates a scenario that the engaging component of FIG. 8 is separated from the second object. In an engaging module 200 of the present embodiment, a first object 50′, a fixing slot 56′, a second object 60′, an engaging slot 62′, an engaging component 210, a main body 212, a magnetized member 214, an elastic component 220, an electromagnet 230, a magnetized member 232, a fixing portion 232 a, a coil 234, a plane S′, and a first axial direction D1′ are disposed and operated similarly to the first object 50, the fixing slot 56, the second object 60, the engaging slot 62, the engaging component 110, the main body 112, the magnetized member 114, the elastic component 120, the electromagnet 130, the magnetized member 132, the fixing portion 132 a, the coil 134, the plane S, and the first axial direction D1 illustrated in FIG. 1 to FIG. 6 and thus, will not be repeatedly described hereinafter.
The engaging module 200 is different from the engaging module 100 in that the first object 50′ has a pivot 58, and the engaging component 210 has a pivoted end 210 a and a free end 210 b. The engaging component 210 is not slidably disposed on the first object 50′, but is pivoted to the pivot 58 of the first object 50′ along a third axial direction D3 through the pivoted end 210 a. The third axial direction D3 is perpendicular to the moving plane (i.e., the plane S′) of the engaging component 210. Additionally, the elastic component 220 is not a compression spring, but an elastic piece. The elastic piece leans against the free end 210 b of the engaging component 210, such that the engaging component 210 is positioned through an elastic force of the elastic component 220 in a state shown in FIG. 8 to be engaged in the engaging slot 62′ of the second object 60′. The engaging component 210 is adapted to resist the elastic force of the elastic component 220 through a magnetic force generated by the electromagnet 230 to pivotally rotate to the a state shown in FIG. 9 to separate from the second object 60′. Thereby, the first object 50′ and the second object 60′ may be separated from each other.
In the embodiment illustrated in FIG. 8 and FIG. 9, the number of the electromagnet 230 is, for example, one. In other embodiments, the electromagnet 230 may be in any other appropriate number, but the invention is not limited thereto. Additionally, the first object 50′ has a positioning rib 59 use to fix the elastic component 220 to the first object 50′. In other embodiments, the elastic component 220 may be fixed by using any other adaptive structure, and the invention is not limited thereto.
FIG. 10 is a perspective diagram illustrating part of components of an engaging module according to another embodiment of the invention. In the embodiment illustrated in FIG. 10, an engaging component 310, an elastic component 320, and an electromagnet 330 is operated similarly to the engaging component 110, the elastic component 120, and the electromagnet 130 illustrated in FIG. 1 and thus, will not be repeatedly described hereinafter. The embodiment illustrated in FIG. 10 is different from the embodiment illustrated in FIG. 1 in that the engaging component 310 is not composed of the main body 112 and the magnetized member 114 as the engaging component 110 illustrated in FIG. 1, and the engaging component 310 is an integrally formed magnetized member. The elastic component 320 includes two elastic arms respectively connected with two opposite sides of the engaging component 310. The electromagnet 330 is adapted to drive the engaging component 310 to resist an elastic force of the elastic component 320 through a magnetic force generated to the engaging component 310.
In light of the foregoing, the assembly and disassembly of the objects is performed by the engaging module through the movement of the engaging component in the invention, instead of by using the deformation of the hook itself in the way like the conventional hook does. Thus, the amount of interference between the engaging component and the object interfered with each other is not limited and therefore, have better engaging capability. In addition, since the engaging module is not operated through the elastic deformation of the engaging component as described above, the minimum length of the engaging component is not limited by the need of the elastic deformation, which contributes to thinning the appearance of an apparatus applying the engaging module. Moreover, in the engaging module of the invention, the engaging component is driven to move by using the magnetic force generated by the electromagnet, instead of by using a force applied by a user, and thus, the engaging component can be prevented from being fractured due to the force applied by the user. Meanwhile, the engaging component does not have to be exposed for the user to apply the force, such that the apparatus applying the engaging module may have better appearance. Moreover, the direction along which the first object and the second object are combined or separated is designed as being perpendicular to the moving plane of the engaging component, such that the engaging component is not driven to move due to the relative movement of the first object and the second object, such that the risk of the engaging component being accidentally separated from the second object can be reduced.
Although the invention has been described with reference to the above embodiments, it will be apparent to one of the ordinary skill in the art that modifications to the described embodiment may be made without departing from the spirit of the invention. Accordingly, the scope of the invention will be defined by the attached claims not by the above detailed descriptions.
